and there
are hotly debated signals in detectors for these two possibilities. Inflation,
which seeks to explain the large-scale homogeneity and isotropy as well as the
oldness of the Universe, produces the density fluctuations that are responsible
for formation of structure as well as gravitational waves. The basic
predictions of inflation have proven true, and individual

models
are now being tested. Most models have been ruled out, and my model of Natural
Inflation is a good fit to all data.

I will
discuss recent excitement about claimed detection of gravity waves at the South
Pole, and will end with a discussion
